BOTTLE CLOSUBE.'

Application illed October 7, 1926, Serial No. 140,081. Renewed December 3, 1928.

This invention relates to bottle closures and has for an object to provide a closure for the type of bottle or jar ordinarily known as a milk bottle, embodying new andimproved features of convenience and sanitation. A further object of the invention is to provide a bottle closure embodying vthe features of the well known pouring pull but improved in that a liner is employed under the scored disk.l l

A further object of the invention is to provide a disk with a liner associated'therewith in position normall;y under the disk in operation upon a bottle, said disk being scored `from the under side, such scoring alsoV completely severing the liner in registering withtlie scoring, so that-the scored part of the disk may be lifted with the severed part of the liner therewith.

A further object of the invention is to provide a disk and liner secured together in any approved manner, one of which is a staple or the like passing through the liner and through the disk with a scoring of the disk from thel under side cutting the liner about the staple in such manner that manipulating the staple will cause a fracturing of the disk at the scored line, permitting the raising of the scored section with that section of the liner secured thereto by the staple.

yWith these and other objects in view, the invention comprises certain novel parts, elements, features, combinations'and functions as disclosed in the drawing together with H mechanical and functional equivalents thereof as will be hereinafter more fully described and-claimed.

'In the drawings:

Figure 1 is a view of the invention by the exhibition of a bottle partly in section andy partly in. elevation with the closure applied .thereto shown substantially in diametrieal section, the section passing also through the pouring pull. f

Figure 2 is an inverted plan view of the closure, a part of the liner being broken away to show the disk.

Figure 3 isa top plan view of the closure as it appears upon and in cooperation with the bottle. v

Figure 4 is a diametrieal sectional view through the closure removed from the bottle but in cooperative shape with the pouring pull shown in open position as takeny on line of Figure 3.

Figure 5 is a diametrieal sectional viewthrough the device before being applied to a bott e as taken on line 5-5 of Figure 2.

Like characters of reference indicate corresponding parts throughout the several views. 4

The improved bottle closure which forms the subJect matter of this invention is adapted to be applied to various bottles, jars and the like and the illustration at 10 of a conventional milk bottle is not intended as any limitation upon the invention or its utilities or functions. Whatever the shape of the bottle or lts nominal utility, it will be provided with a neck rabbet 11`forming a shoulder upon which in the usual and ordinary use of the bottle a card board disk rests forming the closure.

- The present invention embodies also a card board disk 12 secured to which is a liner 13 upon what is the normally under side of the disk as it is applied and as shown at Figure 1. This liner may be of anyapproved material such for instance as a thin paper impregnated with parait'ine or other waxy material or a resinousconipound which will harden, and the invention is in no way limited to the precise nature of the liner.

The liner may be attached to the disk 12 over its entire surface by melting the wax or other impregnating material, if desired, but such attachment forms no partof the present invention. Under the present invention, the liner 13 is attached to the disk 1 2 bymeans of a staple -14 which may be the only attaching means or may be merely supplemental. The staple 14 may and preferably will also attach a tab 15 for convenience of operation, but such tab is no limitation upon the invention. About the staple 14 or its position, the disk 12 is'scored, as shown at 16, from the normally under side stopping yshort of the upper surface, so that there remains uncut a thin portion of the disk on the upper or outer side, so

that 'the disk in position upon the bottle willtute means, the scored section of the disk together with the severed section of the liner' may be raised 'forming an openingbthroiigh the superposed disk and liner for the insertion of astraw, if desired, or serving las an opening v merely "pouring out the contents of the bottle;

The severing of the upper or outer surface of the disk also forms a pouring pullwhich will closev into closed position after a part of the contents have been removed as distinguished from the seorih from the top which leaves a jagged edge a ut the pouring pull which prevents its being returned to normal seating. With the fractured edge outermost, however, there is nothing to prevent the accurate return of the pouring pull to completely fill the openrate and neat folding of the several crimps.

Such folding or crimping is, however, not any part of the resent invention which includes the liner under the disk and is not in any Way limited to the extent,vformationv or disposition of the marginal portion of said liner. i

f, What I claim to be new is:

relatively stiff sheet material, an Independent liner of relatively flexible material under the disk and extending as an annulas therebeyond, scoring passing through the liner and into the 1. A bottle closure comprising `a disk o f'` disk to form registering lips, and means passing through and securing the lips together to lift eonjointly.

2. A bottle closure comprising a disk of relatively stift' sheet material, an independent liner of relatively flexible material under the disk and extending as an annulus therebeyond,

scoring passing through the liner and into the disk toform 'registering lips, a lifting tab and means passing through and securing the tab and lips together to lift eonjointly.

In testimony whereof I affix my signature.
